Princess Beatrice and Eugenie of York also attended; they later headed to a travel awards show at the Savoy Hotel wearing the same outfits. Eugenie's ring was the most prominent piece of jewelry worn by either of them.

Even more royals, including the Countess of Wessex and Prince and Princess Michael of Kent, attended this year's opening day, but I don't have better pictures of them to share with you at the moment. (No need to try to link other photos. I have seen pictures, but I mean that I don't have any that I can share legally here.) If other images become available, I will share them here.
